What are some good overnight beauty treatments?

My husband will be out of town for a night. I plan to use this time to do some overnight hair and skin treatments (as he doesn’t like me going to bed covered in “sticky stuff” lol).

What do you like to use for overnight hair and skin masks? Any other ideas for overnight treatments?

Some thoughts I had were:

Some sort of hair mask

Some sort of face mask

Some sort of hand mask with gloves to keep it in

Some sort of foot mask with socks to keep it in

Some sort of full body mask

I just don’t know wear to start!
